  • the invention relates to an arrangement for the mechanical treatment of water-suspended pulp fibers between two treatment gap forming, relatively rotating and coaxially arranged treatment plates, which are arranged in a closed housing with an inlet and an outlet for the fiber suspension.

  • the treatment plates must be optimally adapted to the pulp to be treated, also to prevent excessive wear of the same.
  • the object of the invention is therefore to simplify the construction of such arrangements. According to the invention, this object is achieved in that rotating treatment plates are mounted in the housing and connected via a drive shaft with an existing outside of the housing gear or drive. Due to the separate storage of the rotating treatment plates, the load on the drive shaft can be significantly reduced, which has a corresponding effect on their design and storage. As a result, the required space and the corresponding manufacturing costs are significantly reduced. This in turn allows to store the drive shaft only outside of the housing.
  • the drive shaft is designed in one piece with an axis of the transmission or the drive.
  • the drive shaft can be completely dispensed with a direct storage.
  • the transmission or the drive should advantageously have a drive pin for non-positive or positive reception of the corresponding end section of the drive shaft designed as a hub or a drive hollow shaft for frictionally receiving the corresponding end section of the drive shaft.

  • the treatment surfaces of the treatment plates may be perpendicular to the axis of rotation or conical to the axis of rotation. It is also possible that several treatment gaps are present in the housing. In this case, to fully exploit the advantages of the invention, the rotating treatment plates of the treatment gaps should be driven by a common drive shaft.

Abstract

L'invention concerne un dispositif pour le traitement mécanique de fibres de pâte à papier en suspension aqueuse entre deux plaques de traitement (2,3) qui sont disposées coaxialement l'une par rapport à l'autre en formant un interstice de traitement (1), qui effectuent un mouvement rotatif l'une par rapport à l'autre et qui sont agencées dans un logement (4) fermé équipé d'une amenée (5) et d'une évacuation (6) pour les fibres en suspension. L'objectif de la présente invention est de simplifier cette structure. A cet effet, les plaques de traitement (2,3) rotatives sont montées dans le logement (4) et reliées à un mécanisme de transmission (8) ou d'entraînement (9) situé à l'extérieur du logement (4) par l'intermédiaire d'un arbre d'entraînement (7).
